This is my first post to the group, & I've probably started out doing my search for data wrong, cuz' no matter what I type in the Search Bar, it keeps giving me the basically the same 4 pages of topics that are not specific to what I'm looking for.

I've got a Customer that wants to "Temporarily" set up a RV Trailer, till next Spring, on the site where a Mobile home was set up. Their is a metered 200 Amp Outdoor Disconnect already installed from 2006 with spaces & feed through lugs.

The Trailer power requirement is 30 Amp/ 120 Volt, & I want to add a 20A. GFI, so I'm looking at possibly a Connecticut 30A RV PANEL W/ 20A GFCI, or something similiar From C.H./Eaton.

This panel will be posted within approx. ten foot of the RV, & be approx. twenty foot from the Disconnect.

I'm thinking that I should run 8-3 UF to "said" panel.

It's been at least two years since I've installed any power source for a Mobile Home, let alone a RV hookup, & I want to dot my "i-s" & cross my "T-s" before I quote anything to this Customer.

Am I just typing in the wrong search words to find data on an installation like this? I used "NEMA 5-20R2 GFCI" & came up empty.

You can run a regular 5-20 GFCI out there on 12ga UF and use the 30a-20a adapter that most RV guys carry or you could run a 10ga circuit on a single pole 30a breaker and use the 120v 30a receptacle Most RVs will run enough on 20a to make them usable.

The "Customer" after receiving the estimate for that RV Service, , as well as Upgrading his House Service to 200 Amp, as well as installing a 100 Amp sub-panel in his horse barn with "Lights & Outlets", as well as installing in his house a New Condensing Gas Furnace / Heat pump, & well as Duct work in his house, ...... wanted all of it for less than $3000.00, WTH?!?

Needless to say, ... I quickly walked away from that one, & as I have passed by his home since then, ... He hasn't had anything done there.But Again, Thank You Sir!
